clinton or power products?

[paa60]

so I have an old 1959 dual engine kart (trackmaster) which was built for 2 engines, I have 2 good Clinton 500's (look just like the 490 but newer I think) and I have 2 power product AH47, all 4 are good, but wondering which ones are better? better I mean running idling and performace?

thanks

Go with the Clinton's! ...but that's just personal preference. I don't think anyone ran the AH47's back in the day...could be wrong though

Clinton 500= 5.8 cubic inch, Power Products AH47= 4.7 cubic inch, Clinton is a bushing engine, AH47 may be bushing or needle bearings. Both are cross scavenged engines. I would use the Clintons.

WE USED TO RUN AH58s ON OUR KARTS BACK IN THE DAY--THEY ATE MACS!

I'd run the engine pair based off what has the best parts availability. I'd say the Clinton engines would have more support but I could be wrong.
